Worth Watching: ..., an 'Evil' TwistEvil (10/9c, CBS): Nearing its own first-season finale, Evil reaches back to its season opener, reintroducing the chilling killer Orson Leroux (Darren Pettie), who's trying to get his conviction overturned with the help of the malevolent Leland Townsend (Michael Emerson). This forces Kristen (Katja Herbers) to go back into court at the worst possible time, as her daughter Laura (Dalya Knapp) is undergoing emergency heart surgery. Back on the fighting-evil job front, a recovering David (Mike Colter) — having survived last week's terrifying ordeal in the hospital — visits a woman seeking spiritual advice and is shaken after witnessing her less-than-pure instincts.
